Today, many organizations running COBOL applications are exploring options to move these applications to object-oriented Java applications. Many options are available, such as rewriting the code, reengineering mainframe applications, extracting business logic, or using automated conversion tools.
Automated technology to convert COBOL applications to object-oriented languages is a practical approach to modernization. Customers often pursue this approach with millions of lines of code and tens of thousands of COBOL programs. Fully automated refactoring tooling can ensure successful mainframe modernization projects with a high return on investment.
In this article, we’ll provide a high-level overview of Astadia’s approach to automate the migration of mainframe workloads to the Google Cloud Platform.
IBM and Unisys mainframe applications are mission critical systems. These legacy systems are often not documented, with decades-old code, and the people who wrote these applications have usually moved on years ago. As a result, a high-quality and thorough mainframe assessment is an important first step.
Tools such as Micro Focus Enterprise Analyzer and Astadia’s mainframe analysis tooling offer a rich insight into legacy applications.
A complete assessment will offer many reports and analyses, but the primary goals of the assessment phase are to:
Astadia follows the same methodology for each project, ensuring the migration is completed as fast as possible while minimizing risk. Astadia FastTrack accelerates mainframe to cloud projects and allows us to manage risks associated with digital transformation effectively. FastTrack enables complex cross-platform migration of core business applications while routine maintenance occurs without interruption.
Google Cloud Platform is a popular target for enterprise customers migrating COBOL applications and other legacy technologies off the IBM Mainframe.
Below is a high-level reference architecture of a mainframe to cloud deployment on GCP with Astadia.
The newly transformed applications run natively on Google Cloud. Astadia technology does not rely on emulators or sandboxed applications.
Our tooling keeps the transformed code concise, readable, and maintainable, without code bloat, centralizing code sections within libraries and software services. These become an integral part of the generated code, delivered in source code format. There is no vendor lock-in, and newly written code does not need to rely upon the source libraries.
There are many benefits of migrating IBM Mainframe applications to Google Cloud Platform. Some customers are pursuing cost savings, and typically a mainframe to cloud migration results in 60-80% annual cost reductions.
For others, migrating mainframe applications to Java is a way to address mainframe talent and skills shortage.
For even more customers, these migrations are strategic. For example, customers often want to leverage analytical capabilities and benefit from Google Cloud’s machine learning solutions.

Organizations keep discovering new and improved benefits for moving their mainframe workloads to Azure.
As technology advances, mainframe organizations are increasingly pressed to transition to more modern platforms. Here are some of the most common misconceptions that hinder their mainframe modernization journey.
The cost of not modernizing mainframe systems is generally far greater than the time, effort, and money required to make the transition. Here's why.
As mainframes host mission-critical applications, it's essential to ensure that the modernization process is accurate and causes minimal disruption to business operations. This is where automated migration and testing tools come in.
